AutoBros Pre Treatment Spray has been specially formulated and developed with a blend of solvents that remove residual oils and waxes which might interfere in the bond between coating and paint. It contains no silicones and is an extremely important auto detailing product as it helps in the removal of any light/ minor left over wax, sealants or glazes and in the process, reveals any minor scratches or swirl marks that haven’t been corrected but have simply been hidden underneath the layer of fillers or oils.
